如何在python中插入换行符xml.etreemodu装置

Question

我想打印出这样的xml：

<xml>
    <tag>
        this is line 1.
        this is line 2.
    </tag>
</xml>

我有一段代码是这样的：

^{pr2}$

但打印出来是这样的：

<xml>
    <tag>this is line 1.&#x000A;this is line 2.</tag>
</xml>

当我使用'\n'而不是'
'时，输出如下：

<xml>
    <tag>this is line 1. this is line 2.</tag>
</xml>

如何在“this is line 1.”和“this is line 2”之间插入newline

Answer 1

使用'\n'生成新行，即

from xml.etree import ElementTree as ET
xml = ET.Element('xml')
tag = ET.SubElement(xml, 'tag')
tag.text = 'this is line 1.' + '\n' + 'this is line 2.'
tree = ET.ElementTree(xml)
tree.write('test.xml')

会产生

^{pr2}$

这相当于

<xml>
    <tag>
        this is line 1.
        this is line 2.
    </tag>
</xml>
